Abstract

Wireless sensor and actuator networks (WSAN) are an important part of the emerging Industrial Internet of Things concept. Providing a computationally simple but relatively accurate analytical quality of service (QoS) model for the wireless communications technology is an essential step in developing distributed adaptive network protocols which try to satisfy the stringent industrial QoS requirements. In this paper, a novel Markov chain analysis and delay model has been proposed for the IEEE802.11-based WSANs applications which improves the accuracy while maintaining simplicity and considering the implicit industrial characteristics. Simulation results prove its superior performance compared with similar works.
